(heating elements, hot air ducts etc.), equipment con-
taining powerful magnets (large diffusers, etc.), areas
affected by direct sunlight, rain, humidity, excessive
dust, mechanical vibrations or shocks
- in compliance with safety standards, the device must
be installed correctly and in a way to protect against
any contact with electric parts; all parts that ensure
protection must be fixed in a way that they cannot be
removed without the use of tools.

Solutions:
-
check the room temperature; see A1 parameter
Main consequences:
-
the device will continue to operate normally
AH Maximum temperature alarm
Solutions:
-
check the room temperature; see A4 parameter
Main consequences:
-
the device will continue to operate normally
id Door switch input alarm
Solutions:
-
check the causes of the activation of the input;
see i0 and i1 parameters
Main consequences:
-
the effect established with the i0 parameter
iA Multifunction input alarm or pressure switch alarm
Solutions:
-
check the causes of the activation of the input;
see i0 and i1 parameters
Main consequences:
-
the effect established with the i0 parameter
COH Condenser overheated alarm
Solutions:
-
check the condenser temperature; see C6 pa-
rameter
Main consequences:
-
the device will continue to operate normally
CSd Compressor shut down alarm
Solutions:
-
check the condenser temperature; see C7 pa-
rameter
- switch the device off and back on again: if
when the device is switched back on, the tem-
perature of the condenser is still higher than
that established in C7 parameter, disconnect
the power supply and clean the condenser
Main consequences:
-
the compressor will be switched off
dFd Defrost alarm switched off because maximum time
has been reached
Solutions:
-
check the integrity of the evaporator probe; see
d2, d3 and d11 parameters
- press a key to restore normal display
Main consequences:
-
the device will continue to operate normally
When the cause of the alarm disappears, the device restores
normal operation, except for the following alarms:
-
compressor shut down alarm (code “CSd”) which re-
quires the switching off of the device or the temporary
suspension of the power supply
- defrost alarm switched off because maximum time has
been reached (code “dFd”) which requires the pressing
of a key.
7 ERRORS
7.1 Errors
Code Meaning
Pr1 Room temperature probe error
Solutions:
-
check that the probe is the PTC or NTC type;
see P0 parameter
- check the device-probe connection
- check room temperature
Main consequences:
-
compressor activity will depend on C4 and C5
parameters
- the defrost will not be activated
Pr2 Evaporator probe or condenser probe error
Solutions:
-
the same as in the previous example, but with
regard to the evaporator probe or the condenser
probe
Main consequences:
-
if P4 parameter is set at 1, the defrost interval
will last for the amount of time set with d3
parameter
- if P4 parameter is set at 1 and d8 parameter is
set at 2 or to 3, the device will operate as if d8
parameter were set at 0
- if P4 parameter is set at 2, the condenser over-
heated alarm (code “COH”) will never be acti-
vated
- if P4 parameter is set at 2, the compressor shut
down alarm (code “CSd”) will never be acti-
vated
When the cause of the error disappears, the device restores
normal operation.

3 USER INTERFACE
3.1 Preliminary notes
Operating statuses:
-
“on” status (the device is powered and is on; utilities
may be on
- stand-by” status (the device is powered but is switched
off via software; utilities are off
- the “off” status: the device is not powered; utilities are
off.
Hereafter, if the POF parameter is set to 0, with the word
“switch-on” means the passage from “off” status to “on”
status; the word “switch-off” means the passage from “on”
status to “off” status.
If the POF parameter is set to 1, with the word “switch-on”
means the passage from “stand-by” status to “on” status; the
word “switch-off” means the passage from “on” status to
“stand-by” status.
When the power is switched back on, the device displays the
status that it was in at the time it was disconnected.
3.2
Device switch-on/off
If the POF parameter is set to 0:
1.
Connect/disconnect the device power supply.
If the POF parameter is set to 1:
2.
Make sure that the keyboard is not locked and that no
procedure is in progress.
3. Hold the key for 4 s: the LED will flash, after
which it will turn off/on.
3.3 The display
If the device is switched on, during normal operation, the
display will show the magnitude established with P5, except
during defrost, when the device will show the temperature
established with d6 parameter.
If the device is switched off, the display will be switched off;
the
LED shall be on.
If the device is in "low consumption" mode, the display will be
switched off and the LED shall be on.
3.4
